(creed-+22) I 7 This invention relates to dispensing containers for light, powdery materialsssuchas insecticide powders, for example. More particularly, the invention relates to a container of the type inwhich air pressure is usedfor theexpulsion ,of-the container contents, the air pressure being produced by depression of one or more of the container walls.

The invention" has for itsuprimary object'the provision of a dispensing container which: is of simple and inexpensiveconstruction; and which is of suchsize anda'shape'asito enable its contents tobe convenientlyc and effectively directed to the desiredregionsfwithout waste of such contents; as: to enable it to eifectiveiy display,- when on a counter or the'like,=theprinted matter on "its exterior wall surfaces, and as to: enable a plurality: of such containers to be compactly handled, shipped and stored; 4 1

A further object of the present invention is: the provision of a dispensing container which is formed from-a simple and inexpensive blank of cardboard or 'lik'e 'ma'terial*having parts which are readily and "conveniently foldable to provide a chamber or compartment-for the container 'contents; other parts which" are readily and conveniently fold'a'ble'to cover in whole or in part said chamber or compartment after'it has re ceived such contents, and other parts which are readily and conveniently fold'ableto 'se'a1 said chamber or compartment and complete the formation of'th'e container. I

A' further object ofthe present invention is'the provision-of a' container blank which: is so constructed andarran'gedas to not onlyenable a chamber or compartment to be'readily and rapidly formed by simplefolding of certain parts of the blank but also, to enablesaid part to be seli maintaining in their folded relationship, therebymaking it unnecessary to maintain the chamberor compartment bythe useof adhesive or other independent fastening m ans,

It also is; to be understoodthat the phraseology or terminology herein employed is for purposes of description and not of lim'itation, the scope of the present invention being denoted by'the ape pendedclaims. 4 o T I The blanlc- I0 irom which the present container is formed is shown in Fig. 1 in its initial fiat condition, said blank being made of deformable sheet material, such as cardboard of suitable grade and thickness and being produced by a simplea-nd inexpensive stamping operation. -As shown-,the blank comprises a relatively elongated central. strip and two opposedside wings which may beand here areiidentical; The central strip consistszof asuccession,- of integrally connected rectangular .portionsrlLJl, 13, I4 and i5 To facilitate the folding of four of. such portions in the manner hereinafter referred to, said central strip istransversely scored or indented between adjoining rectangular portions thereof the fold lines so formed being designated by the {reference numerals lii, I1, 18 and l9.--.Each side wing ofthe; blank comprises two rectangular 1 portions "(those ofone vwingbeing designated by the referencenumerals 2 0 and 21 and the correspond.- ing portions of the otherwing being designated by. the reference numerals 20a and Zia) and one triangular portion (that of one wing being des} ignatedby the reference numeral 22 and the cor responding portion of the other wing being desnumerals Meandjia, Afold line also is provided between, the central stripiand each wing, the 'fold; line 26 lying between the central? strip portion I3 and the triangular portionlz of, one W n andthetfold line 26a lying between such central strip portion and the corresponding tri angular portion 22a of the other wing.

irrne b k fi q d 'iq r vi e eat-e or compartment for the light, powdery material which is to constitute the container contents, said material being omitted from the drawings for simplicity of'illustration;, To thatend; the wing portions" 20' and 20a are swung inwardly, about their respective fold lines 24 and 24a. The porp the upper surfaces of the wing portions 2| and tions 2| and 22 are next jointly bent upwardly, I about the fold line 26, and the portions,2l t g t d 22a are jointly bent upwardly about the fold-iline,

26a, so as to bring the portions 22 and 22a to substantially upright positions,substantially normal to the central strip [3. The'portions 20;: and 20a will then overlie the fold line H of the central strip. As here shown, the wing portions and 2041 are of such'length or lateral extent that they meet at substantially the middle of the fold line [1, although they may be of greater or less length, if desired. Inasmuch as the fold lines 24 and 240, are inclined with respect tothe central strip, and to the fold line IT to which the fold lines 24 and 24a lead, the wing portions 20 -and'20alie when so-folded in a plane forwardly inclined with respect to the plane of the. central strip,"as will be evident from Figs. 3,- 4, 5 and 7.

Portions I-land I2'are next jointly-bent upwardly andsli'ghtly forwardly aboutthe'fold line H, portion I 2 beingbrought into engagement withthe rear surfaces of the forwardly tilted wing portions 20 and'20a, and portion =l| being turned downwardly and slightly rearwardly, about the fold'line IE, to bring it-into engagement withthe frontsurfaces of said wing portions 20 and 20a, which are thus sandwiched between the central strip portions II and I2 (see'Fig. 3). The length of portion H is slightly greater than the verticalfdistance between-the top of the forwardly tilted portion 7 l2 and the central strip portion 13 therebelow (the vertioaldistancebeing indicated by the dotted lineX in Fig. 3), and-as a result,-portion it must be forcibly swung rearwardly into engagement with the wing portions 20 and 20a. There is thus a'frictional resistance the forward movement of the lower tucked-in edge 'of'portion H, which effects a looking together of the fourportions (the central strip :por tions'l I and l 2 and the wing portions 20 and 20a) which constitute the rear wall of the container.

The chamber or compartment thus provided (and which is self-maintaining by the locked in bottom edge of portion) is of prism-like con tour, with a generally rectangular; rear wall (heretofore referred to) and generally triangular side Walls formed bythe wing portions 22 and 22a. As the chamber or compartment is open at its top, it may be easily and'conveniently filled with insecticide powder or other material of light; powdery nature. I

Thereafter, the wing portions ZI -and 21a, are

lines 25 and 25a to cover, in whole or in .part,

the now filled chamber or compartment. As here shown; saidwing portions are of such size as to jointly cover the entire chamberor compart ment,"as will be evidentfrom Fig. 2. Although the width of these wing portions may be reduced, it is quite desirable for-sealing purposes that their length besubstantially the sameas that of the chamber or compartment at its top aswill hereinafter'more fully appear. r

Adhesive material is next applied to the upper surfaces of the central strip portions l4 and 15, and as such portions project forwardly in 'substan' tially flat form from the chamber or compartment, the application ofrthe'adhesive' to such surfaces can b'eeasily, quickly-and conveniently 21a which cover the chamber or compartment. ;',Iheend portl0rl is then bent downwardly, :about ,thetfold line I9, to bring it into contact with and securement to the rear surface of por- "tion l2 which-"constitutes the outer part of the i nt inen eer, Wa

This completes the formation of the container and'the sealing of its contents, as will be readily understood. To permit ejection of such contents, in .useithereof, .eitherone or bothof the front corners of the container may be cutaway by the purchaser of: the container; or such purchaser may notch the .front edgeof the container atany place along:;.such=.;edge to. provide a discharge opening; To indicate the desirability of discharging the contents oflthe container from its front edge, ared dot 30 may be placed at each end of such"edge and-a-similar dot. 3| may be placed at the middleof suchedge, all on the upper surface of portion I4, asshown in Figs..1 and 4. The container contents aresexpelled, of course, by air pressure producedby depression of one or more of the container walls, such as by simultaneous depression of its flat bottom wall and its sloping top wall, all in a manner which will be readily understood. I

. The shape of the container is such that it can be easily and conveniently grasped and its contents effectively directed, without waste of such contents, to, the desired areas. Moreover, its shape enables printed or advertising matter on its exterior surfaces to, be effectively displayed whenthegwntainer is positioned on a counter 01' the-like, and asthe blanl; from which the eontainer is madehas an initialflat form, it is a simple matterto print on that. surface thereof vvhich c nStitutes the exterior. surfaces ,of the container. Furthenits shape enables a plurality ofcontainersto be compactly handled, shipped and stored, as indicated: by Fig. '7 which shows two containers in superposed complementary relationship. Thechamberor compartment of the container is formed by'isim'ple bendingof certain parts of the inexpensive blank from which the container is formed, and the chamber; or compartment is self-maintaining by the locking arrangement ,of its rear. wall parts.
